The Super Assassin kinda looks like one of those exaggerated anime swords. Appears to cut like one, too.I kinda like that actually, the Super Assassin has such a wide blade that it almost doesn't look like a wakizashi anymore. I'm sure for performance reasons the SA is optimized but it just doesn't look a ton like a wakizashi anymore aesthetically.
Are you thinking of a handle that reflects traditional handle shaping at all, or are you thinking to make a race sword-type handle like the K18?
